Abstract: A step determination device includes an operation amount sensor that detects an operation amount of a braking operation member, and a controller that determines a step by using the wheel speed and the operation amount. In the step determination device, the controller calculates an actual variable amount by using the wheel speed, calculates an estimated variable amount corresponding to the actual variable amount by using the operation amount, and executes the determination of the step by using the actual variable amount and the estimated variable amount. For example, the controller determines the presence of the step when the deviation between the actual variable amount and the estimated variable amount is not less than a predetermined value, and determines the absence of the step when the deviation is less than the predetermined value.

Abstract: A brake system includes a brake activator which controls, when a slipping condition is detected at a central rear wheel based on a signal detected by a central rear detector, the operating condition of a central rear brake based on the signal detected by the central rear detector so as to reduce a braking force on the central rear wheel lower than a braking force which is obtained as a result of operation of an input member. In this state, when an operation quantity of the input member increases as a result of operation of the input member, changing the operating conditions of both a right front brake and a left front brake, the brake activator increases the braking forces in both a right front wheel and a left front wheel according to an operation quantity of the input member.

Abstract: In the case that the road surface is determined to have different friction coefficients on the left and right wheels, this braking control device performs antiskid control for adjusting the increase slope of front wheel braking torque on the side with the higher friction coefficient. A steering angle sensor detects the steering angle, and a yaw rate sensor detects the yaw rate. The device calculates a reference turning amount on the basis of the steering angle, calculates an actual turning amount on the basis of the yaw rate, and sets the increase slope on the basis of the deviation between the reference turning amount and the actual turning amount. Also, if this deviation becomes larger, a correction is made such that the set increase slope becomes smaller. Further, if the deviation becomes smaller, a correction is made such that the set increase slope becomes larger.

Abstract: Anti-skid control is performed by switching between a reduction mode for reducing braking torque and an increase mode for increasing braking torque based on a comparison between four wheel speeds and vehicle body speed. A controller calculates wheel accelerations based on wheel speeds and includes a control mode condition where the reduction mode is selected at each wheel and a wheel acceleration condition where each wheel acceleration is within a predetermined value range. If a state in which the control mode condition and the wheel acceleration condition are simultaneously satisfied is maintained over a predetermined time period, the controller determines that a residual state is satisfied. When the residual state is not satisfied, the controller calculates vehicle body speed based on the maximum value of the wheel speeds, whereas when the residual state is satisfied, the controller calculates vehicle body speed based on the minimum value of the wheel speeds.

Abstract: A vehicle brake control device performs select-low anti-lock brake control. In the select-low anti-lock brake control, in a decrease period, in which braking force on a first wheel that is one of left and right wheels that has a lower wheel speed is decreased, braking force on a second wheel that is one of the left and right wheels that has a higher wheel speed is also decreased. In an increase period, in which the braking force on the first wheel is increased, the braking force on the second wheel is also increased. The vehicle brake control device is configured such that, when performing the anti-lock brake control, the vehicle brake device sets the braking force on the second wheel to be greater when the tendency for instability in the vehicle behavior is small than when such tendency is large.

Abstract: A vehicle brake controller is capable of executing limit control for limiting increase in braking force applied to front wheels by using a deceleration of a vehicle. The vehicle brake controller is configured to start the limit control when the deceleration of the vehicle becomes greater than or equal to a start determination value before a start determination time period elapses after a deceleration starting point in time, at which the deceleration of the vehicle is started by application of braking force at least to the front wheels. The vehicle brake controller is configured to end the limit control if the deceleration of the vehicle is less than an end determination value, which is greater than the start determination value, at a point in time when an end determination time period, which is longer than the start determination time period, has elapsed from the deceleration starting point in time.

Abstract: This vehicle braking control device executes automatic braking control to adjust a braking torque on the basis of a vehicle target deceleration value corresponding to a distance between the vehicle and an object in front of the vehicle, and executes anti-skid control to suppress excessive wheel slip by adjusting the braking torque on the basis of a wheel speed. The braking control device calculates an actual deceleration value corresponding to the target deceleration value, and executes feedback control on the basis of the target deceleration value and the actual deceleration value such that the actual deceleration value approaches the target deceleration value. The configuration is such that a control gain of the feedback control is reduced when anti-skid control is executed. Further, the configuration may be such that execution of feedback control is prohibited when anti-skid control is executed.

Abstract: In a braking control device, a controller is configured to determine an inside and an outside of a turn by using the yaw rate, to calculate a deflection index based on a standard turning amount corresponding to a steering angle and an actual turning amount corresponding to a yaw rate, to reduce the braking torque of the rear wheel on the outside of the vehicle turn based on the deflection index when an excessive deceleration slip of the rear wheel on the inside of the vehicle turn is inhibited during an execution of anti-skid control.
